Trigonometry question! find y. round to the nearest tenth!

tresset_1 [31]

Answer:

Step-by-step explanation:

Look at the picture.

Use sine:

$sine=\dfrac{opposite}{hypotenuse}$

We have a measure of the angle and length of the hypotenuse:

$\alpha=29^o,\ hypotenuse=500\ ft$

$\sin29^o\approx0.48481$

Substitute:

$\dfrac{y}{500}=0.48481$ <em>multiply both sides by 500</em>

$y=242.405\to y\approx242.4$

Answer:

Step-by-step explanation:

Call the first person A who can do the job in 5 hours.

Call the second person B who can do the job in 7 hours.

The formula for this problem is

Time = A*B/(A + B)

Time = 5*7 / (5 + 7)

Time = 35 / 12

Time = 2 hours and 11/12 of an hour.

Lilium Inc., an automobile company, estimates a total factory overhead cost of $1,500,000 for the year and an activity base of 2

Jobisdone [24]

Answer:

The applied factory overhead cost is $1,875,000

Step-by-step explanation:

Overhead cost = $1,500,000 at activity base of 200,000

We assume that the overhead is directly proportional to the activity base;

The cost per direct labor = $1,500,000/200,000 = $7.5

Therefore at actual labor hours of 250,000, the factory overhead cost is therefore = $7.5 × 250000 = $1,875,000.
